I chose to use the stock thermal compound on my H70. I had to twist it and it may have popped up once or twice while mounting it. Is this a botched seating? The tubes were so short that it was very hard to put it on.

Excalibur's are ok but if you get the H70 you would probably be better off with a fan that has higher static pressure.
if you're exhausting the push/pull through top center the cooler is not going to have any negative effect on the components below it. that being said, if you're more worried about your GPU temp than your CPU temp, the above setup would be fine.
If you are going to OC, personally, I'd try to make sure the air pulled into the radiator is as cool as i can make it for perhaps an extra 1-2c temp drop.

The H70 has been consistently outperforming the H50 by i think no less than ~5c from what I've read. The science of it is undeniable as well...larger radiator = increase in the cooling performance of a closed loop like this.

Mine is arriving.....Thursday now, damn...if you can wait till then I plan on doing some very detailed independent testing to compare the two.

Is the only real way to make sure the air pulled through the radiator is cool to set the H50/70 up as intake? Can you recommend two fans for the H70? Hopefully the extra money for the H70 is worth it. Thank you.

EDIT: I see the Gentle Typhoons recommended. I thought the Excalibur's were very suited to being used on radiators? Is the GT even better for static pressure than the Excaliburs? Thanks again.Edited by For Victory - 8/25/10 at 6:39am

It's probably not to pretty under there =) Not guaranteed but pretty much inevitable that air pockets get induced into the TIM by these kinds of motions.

Might want to try unscrewing the the tension plate completely off the mobo and securing that to the block first and then screwing it back in place evenly, while keeping very light pressure in the opposite direction with the hand holding the block so the TIM doesn't smear until all the screws are back in and ready for tightening and you've positioned the hand not holding the screwdriver to enable you to keep a steady pressure on the block while you finish tightening., j

that was easiest for me as it a stretch to the front of my case and had similar problem.

I use Silverstone FM123's right now and am very happy with their performance. For me the sound does not matter at all as I usually have more noise going on outside my pc than in so if I was going to get different fans I would probably try out a pair of Silverstone's Air Penetrator fans. http://www.youtube.com/v/8m8fC809TK0&color1=0xb1b1b1&

that looks like it would be a fun rad fan xDEdited by slimbrady - 8/25/10 at 6:53am

Having read through a lot of the forum I feel guilty asking a question about fan setup, but my situation is as follows:

Have the H70, with a push->shroud->rad->pull configuration. It's too large to fit as a rear exhaust without cutting the case and mounting it sticking out.

My PSU sits at the bottom of my case and there is only one fan available on the bottom, one on rear-top and two directly on top.

My GPU creates a sort of barrier b/w the upper and lower halves of the case.

I'm going to mount the H70 setup in the front 5.25" bay and I'm considering the following to configs. I know this has been beaten to death, but I can't do a rear exhaust and that forces me to do an intake with the H70 (which people disapprove of) or intake air from the top of the case (which people disapprove of).

Edit: the question then being; which looks like a better setup? Thanks.Edited by MicahFett - 8/25/10 at 7:59am
